CHIMNEY-SAFE.

'Specification of. Letters PatentNo.

To all whom t mayv concern.' y Be it known that I, GEORGE B. CLARKE, ofLeonardsville,l Madison county', State of. New York, have invented anewanduseful Improvement in Chimney-Safes; and I .d0- hereby declare thatthe following is a full, clear, and exact description of the same.

The nature of my improvement consists in providing thelower part of thechimney with a smoke box, having a water tank be; low, and regulatingdampers above; the point or points of'v entry of the smoke. l

To enable others skilled in the art to make. and luse my improvement, Iwill proceed lto describe its construct-ion and operation, referencebeing had to the annexed drawings forming a part of this specification,in which- Figure l, is a side sectional elevation of my improvement.Fig. 2, an end sectional elevation of the same. Fig. 3, a horizontalplan section of same;

Similar letters of reference indicate corresponding parts in the severalfigures.

A is the chimney composed of brick, in the usual manner, B the smokebox, C tank or receiver, D stove pipe tubes, E ,wire screen or fender, Ehinged dampers, F vertical plate, J door of the smoke box. (a) aperturesbetween the flange (b) of the smoke box B, and the chimney, (c) tube ofreceiver C.

TheV smoke box B open at the top, is placed under the chimney, itsflanges (b) set in brick and mortar on the beams of the building,v theprincipal part ofthe box hanging below the floor of the chimney room. Itis provided with a door J in the front side and one or more tubes D, forstove pipes in the other sides, the tubes, of different sizes, beingcast in plates of equal sizes, permanently or removably secured in thelower part of the sides of the smoke box. The plates, if removable, maybe vsecured by lianges at their corners or they may be keyed on tostaples or hooks inthe castings, sothat tubes of various'sizes, set onplates of equal sizes may t the aperture in the smoke box. In settingthe chimney,- care should be taken. to leave a portion of the rim orHange (b) of the box outside the brick Work; the rim being slightlyraised to receive water running down outside. Small apertures (a) shouldbe left in the mortar next the rim, that the water may run into the box.

The tank or receiver C, issituated at the lowest. part of; the smoke boxB. beinga part. of ltsmbottom, inthe form. of an inverted cone 1terminating in a small tube (c) er1 nozzlewhich may loe-,stopped by aycork: or faucet. The purpose? oruse of thetank or receiver appendedtothe aforesaid smoke box is to hold water which lfrom -rainorcondensed. smokev or other causef'may `run The water may-.be

down inside the box. drawn olf at thefaucet when .required, -f'or beguidedv by a tin orv lead of the building.

The regulators of thedraft, consist of two pipe toI the reary or moredampers ori' .trapk doors F",a.verti` &c. to fall down between'thesurfaces of they dampers and the sides of the box within. By shuttingdown either of the dampers the draft can be greatly lessened vand in thecase of burning of soot by accident in the chimney the most violentflame within may be deadened, if not quite suppressed by first quenchingthe fire in the stove below, and

then closing both dampers E or all of the dampers, if more than two areused, which may be done throughthe side door (J) of the smoke box; afterwhich, the side door J should be shut,which will nearly close the draftof the chimney. The screen or fender y H is used when the dampers areopen, to arrest falling brick and prevent them from disarranging thestove pipe. A cap should beuirmly set on either of the tubes Dnotoccupied by the stove pipe. The fender E is in two parts that it maybe taken out, or replaced through the side door J of the smoke box. Thevertical plate F is hinged to the fender to equalize the draft ofopposite pipes. In some cases the regulators may be fastened on rotatingrods passing through the front of the box so as to be operated withoutopening the side dooraforesaid.

The smoke-box device, described, forms a distinct intermediate chamberas pit were, and the dampers E E above and the coni cal or otherequivalently 'shaped receiver C below the point of entry of thev smokefrom the stove pipe D, combined, effect a considerable improvement inthe draft et cetera,

lighting the re in the stove, and the smoke' box B be madieto-form a drychamber, both above and below the points of entry of the smoke, thatwill greatly facilitate the draft on starting the fire, and any` aftercollection of wet, as the chimney becomes heated, may

i be allowed to remain inthe receiver C from whence it will 'beevaporated by the action of the heat and warmth of the casting and thusbe made to assist the draft by the vapor rising from below the entry ofthe smoke; or, by closing the dampers E', in case of fire in the chimneyarising from and kept up by burning pieces of paper, rags, or such like,drawn by the draft in a flaming condition from the stove, the vaporrising from the water in the receiver will rapidly extinguish theburning particles or pieces and by their falling into the water below,as well as i by the damping, by the vapor, of the smoke boX B whenclosed', all risk of the fire in the chimney' being renewed or breakingout again, on prematurely or soon opening the dampers E again, will beobviated.

I am aware that a narrow 'frame piece having a damper or valve hasbefore 'been fitted in the chimney above the point of entry of thesmoke, to reoulate the draft pers E above and a conical or other equivalently shaped receiver C below the point or points of entry ofthe smokeas and for the purposes set forth.
